Ezekiel 43:17

“And from the base on the ground to the lower ledge shall be two cubits and the width one cubit; and from the smaller ledge to the larger ledge shall be four cubits and the width one cubit.

‘You shall also take some of its blood and put it on its four horns and on the four corners of the ledge and on the border round about; thus you shall purify it and make atonement for it.

“The priest shall take some of the blood from the sin offering and put it on the door posts of the house, on the four corners of the ledge of the altar, and on the posts of the gate of the inner court.
